Theres nothing we or you can do apart from assisting in killing traitors later on or just wait for karma to go back up.
IMO there should be an admin-only thing that lets them set someone else
s karma, or re-set it all together, either to the default when joining for the first time, or something else.
[Also, I was wondering, say there is an admin on, and somebody gets screwed out of their tater round, is it unreasonable to ask said admin if they can force the screwed-out to be tater another round [not the one immediately after, it'd be obvious]? It is built in to TTT as a cheat, mainly ttt_force_terror, ttt_force_traitor, and ttt_force_detective, and it would just be cool if said person, assuming he was legitly screwed out of a t round, and assuming he asked nicely, could be given another t round - especially given how possible it is to go 5 - 20 rounds without becoming tater again.
